In the TV series, there are numerous beast characters like Ursa the Kermode Bear and Luger the Wolf.

In the novel, the beasts do not become embroiled in the owl-bat conflict.

Shade and Marina return to help the banded bats in the cabin escape before Goth and Throbb can find them, whereas in the novel, they do not turn back and it is assumed the bats were killed by Goth and Throbb.

He is shown attempting to physically prevent Marina from escaping the cabin and urges his followers not to leave when Shade warns of Goth and Throbb's arrival. He brands his followers with different names as part of the initiation process and vehemently shuns non-banded visitors.

Scirocco is portrayed as being more manipulative and hostile in the TV series.

Like his father, King Boreal, he also resembles a great-horned owl instead of a Boreal owl.

Orestes, who does not appear in the novels until Sunwing, is present and plays a substantial role in the story.

Additionally, in the TV series, he resembles a great-horned owl, while he is described as a Boreal owl in the novels. In the novels, they have no familial connection.

In the TV series, Goth and Throbb are brothers-in-law.

In the TV series, it is made of a metallic material resembling bronze or copper.

In the novels, Goth's band is described as being black.

Many smaller aspects of the story were also changed for the TV series: It can also be assumed that some plot points had to be simplified/removed, not only to keep the story appropriate for younger audiences, but to ensure the show's plot could be condensed into thirteen episodes. This was most likely done to maintain the show's TV-Y7 rating, whereas the novel is aimed at a slightly older and more mature audience. Additionally, many of the original story's more grim and violent aspects were heavily toned down in the TV series, which takes a relatively cartoony approach to the story.

Numerous episodes in the latter half of the season include plotlines that were not present in the novel, and some plotlines were altered or removed entirely. The TV series starts out very similar to the novel, but strays from the original story in many parts, especially towards the end. One young bat, Shade Silverwing, dared to break the law. For this, a law was passed that forever condemned the bats to darkness. The bats, being neither birds nor beasts, would not choose sides in the conflict. Alliances were formed and a battle was waged between the two kingdoms to establish the balance of nature and the territorial limits of every species. Long before the first migration, there raged a Great Battle between the Birds and the Beasts.
